Select the cylinder type correctly according to the working requirements and conditions. It is required that there is no impact phenomenon and impact noise when the cylinder reaches the end of the stroke; Cushion cylinder shall be selected; Light weight is required; It is required to select light cylinder; Beijing Oil cylinder Narrow installation space and short stroke are required; It is required to select thin cylinder; It is required to have transverse load, and the cylinder with guide rod can be selected; High braking accuracy is required, and locking cylinder can be selected; It is not allowed to rotate the piston rod, and the cylinder with rod non rotation function can be selected; Beijing Oil cylinder Manufacturer In corrosive environment, corrosion-resistant steel cylinders shall be selected.

Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Beijing Oil cylinder The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. Beijing Oil cylinder Manufacturer In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.

If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Beijing Oil cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Beijing Oil cylinder Manufacturer The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.

Items to be checked when the speed of hydraulic cylinder slows down. 1. Where and what type of oil cylinder has been used for several years, Beijing Oil cylinder What is the working pressure. You don't have any of these. How can I troubleshoot them for you. Check the lower seal if there is internal leakage. 2. It is likely that the internal working pressure of the oil cylinder has decreased. 3. Check whether the system is blocked, Beijing Oil cylinder Manufacturer In addition, check whether the oil cylinder seal ring is damaged, and then check whether the piston rod is damaged. Basically, these aspects can identify the problem.
